The Ingrown Lymphatic Vessels Undergo Apoptosis after the Completion of Cerebrovascular Regeneration

(A) Illustrations of brain vasculature indicate the image areas (red boxes) in panels. All panels are dorsal views, anterior upward.

(B) The ingrown lymphatic vessels disappeared from 7 to 8 dpt (n = 23/26). Arrowheadand arrows indicate the adhering lymphatic and blood vessels, respectively. Note the disappearance of the lymphatic vessel at 8 dpt (dotted arrowhead). Scale bar, 20 μm.

(C–E) In contrast to the control (C) (n = 33/35), TUNEL signals were detected in approximately 70% of the ingrown lymphatic vessels (fli1+kdrl−) (D) (n = 30/33) but in less than 5% of the blood vessels (kdrl+) (E) (n = 8). Two-tailed unpaired t test (p < 0.0001). Scale bar, 20 μm. Data are represented as Mean ± s.e.m., ^∗∗p < 0.001. See also Figure S6.
